We have written a review on MADS-box genes expression in developing floral organs, which has been under-explored as compared to their early role to specify floral organ identity. Congrats to Emma Désert for her first review article as a PhD student! #proudPI @rdplab.bsky.social

🌸 FLOWERING NEWSLETTER REVIEW 🌸 MADS-box transcription factors specify floral organ identity at the primordia stage, but also have late and spatially restricted roles in developing or mature floral organs, which Désert et al. explore in this review 🧬 🔗 doi.org/10.1093/jxb/... #PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Chosen examples of floral MADS-box transcripts or proteins with a precise spatial localization described in developing or mature floral organs. (A) Orchid Phalaenopsis perianth-code. The dorsal sepal, petal, lateral sepal, and lip express different combinations of OAGL6-1, OAGL6-2, OAP3-1, and OPA3-2 proteins, forming complexes with OPI (not displayed here). The lateral sepal shows a further zonation into its upper and lower part, expressing different protein complexes. Adapted from Hsu et al. (2021). (B) During rice floret development, OsMADS2 is distally and laterally enriched in the lodicules, which restricts lodicule elongation (for simplicity, only expression in the lodicule is depicted here). In the pistil, OsMADS2 expression is enriched in the ovary adaxial layers and ovule outermost layers. OsMADS4, in contrast, is uniformly expressed in the lodicule and in the ovule.

@mc-caillaud.bsky.social's talk at #SLS26 suggests actin-mediated regulation allows flexible implementation of a shared core strategy, favouring division perpendicular to the growth axis and symmetric partitioning, while avoiding lateral wall anchoring. www.ens-lyon.fr/RDP/signalis...

📢 Two postdoc positions available in @mc-caillaud.bsky.social's group (RDP lab, ENS de Lyon), part of an ERC Consolidator. Project: how plant cells orient their division, combining cell biology, molecular genetics, and mechanical modelling. 📅 Deadline: 1 Oct 26 | Start: Nov 26 onwards Details 🧵👇

Recruitment flyer for two postdoc-funded positions in Marie-Cécile Caillaud's group (RDP laboratory, ENS de Lyon, France). Across the top run six scientific images: a line drawing of an Arabidopsis seedling with roots; a 3D digital reconstruction of a shoot apical meristem with orange and purple sectors marking cell lineages; a confocal microscopy image of plant tissue with green cell outlines and red/orange fluorescent nuclei; two paired 3D cell models in orange/green and yellow/purple showing division plane geometry; and a fluorescence microscopy image of a dividing cell with yellow microtubule-like structures and cyan nuclei on a dark background. Below, the title reads "Two Postdoc-funded positions" with an ERC logo, followed by "Deadline: 1st of Oct 2026" and "Starting date: Nov 2026 and onwards" in a bordered box. The body text is organised into sections: PROJECT (describing research into how plant cells orient their division, combining cell biology, molecular genetics, and multiscale mechanical modelling, with a link to the team website), CANDIDATE (looking for motivated candidates with a strong publication record, prior expertise in plant cell biology or biophysics as a plus, working language English), ENVIRONMENT (describing the ERC Consolidator project, the RDP laboratory hosted at ENS de Lyon, an international and gender-balanced working environment, and the city of Lyon), and RECENT PUBLICATIONS (three pinned references: Goldy et al. 2026 in Science Advances, Gascon et al. 2025 in Current Biology, and Lebecq et al. 2023 in Science Advances). An envelope icon box at the bottom right gives instructions to send a single PDF (cover letter, short summary of previous research, CV with publications, and contact details for two to three referees) to marie-cecile.caillaud@ens-lyon.fr.
